Title: Improvements in or relating to a process for the manufacture of thermo-setting synthetic resins by the polymerisation of alkylene oxide derivatives
IPC: A61K6/891
Filed: 1944-06-14
Abstract: Thermosetting resins are prepared by polymerizing under the influence of 0.1-5 per cent of an alkaline catalyst, if desired with the aid of heat, products containing at least two ethylene oxide groups which are obtained by the reaction in the presence of alkali of the phenolic hydroxyl groups of a dihydric phenol with epichlorhydrin or a -dichlorhydrin, e.g. as described in Specification 518,057. Suitable dihydric phenols are resorcinol and diphenylolpropane. Suitable catalysts are alkali hydroxides, calcium oxide, sodium amide, diethylamine, dibutylamine, piperidine, piperidine benzoate, the piperidine salt of pentamethylene dithiocarbamic acid, trimethylamine, triethanolamine, the diethylamine salt of diethyldithiocarbamic acid, and also the product of combination of piperidine and benzaldehyde.  The resins may be coloured with organic or inorganic colouring matter.  Filling materials, e.g. asbestos or wood meal or plasticisers may be added to the resins.  In example 1, 1 mol. of resorcin is dissolved in 2 mols. of caustic soda, heated up to 75 DEG  C. and epichlorhydin is added drop by drop with continuous stirring.  Stirring is continued and the product cooled, washed and dehydrated on a water bath.  Piperidine is added to the first material and the mass is cooled.  A resinous product soluble in acetone and benzene is obtained.  It hardens with 1 1/2 hours heating at 100 DEG  C., becoming infusible and insoluble.  In example 2, a similar resin is prepared, employing diphenylol propane in place of resorcin and the piperidine salt of pentamethylene dithiocarbamic acid as the catalyst.  The unhardened resin is soluble in acetone, chloroform, and 1 : 4 alcohol : benzol mixture.  The products are suitable for electrical articles, billiard balls or dentures, or in solution as varnishes.  Specification 477,843 also is referred to. As open to public inspection under Sect. 91, the Specification mentions hydroquinone, dioxydiphenyl sulphone and condensation products of phenols with aliphatic, aryl aliphatic, aryl or cyclo-ketones as suitable dihydric phenols from which the ethylene oxide derivatives may be prepared.  Guanidine and its derivatives are mentioned as suitable catalysts.  This matter forms no part of the Specification as accepted.

Title: Improvements in or relating to internal combustion engines in which the cylinders rotate about an axis parallel to the axes of the bores thereof
IPC: F01B3/00
Filed: 1944-06-16
Abstract: 580,194. Two-stroke engines. GIBBIN, A. W. June 16, 1944, No. 11509. [Classes 7 (ii) and 7 (vi)] In a two-stroke engine, in which a pair of cylinder blocks 13, 18, each containing at least two bores and rotating about an axis parallel to the bores but angularly disposed to the other axis, and pistons 23 in one block are coupled to pistons 24 in the other to produce reciprocation, means is provided for adjusting the compression ratio in some or all the cylinders. As shown, the blocks rotate about axes at right angles, the block 13 constituting a pump for combustible mixture which is admitted by a duct 11 and ports 16, 17, and after compression is transferred by a port 4 and passage 10 to the other block 18. The mixture is admitted to the power cylinders through a port 9, registering with ports 21 as the block rotates and the spent gases are exhausted through port 8 and duct 12. To vary the compression ratio the head of one or both cylinder blocks, or the blocks themselves, is displaced axially automatically, but subject to an overriding manual control, by fluid supplied by the pump cylinders, or mechanically by a screw 29 rotated in a nut 28 by toothed gearing 30, 31. The shaft of the screw bears on a ball thrust bearing 29a. The screw 29 may be coupled to the throttle valve so that the compression ratio is decreased as the throttle is opened. Firing in each cylinder in turn is effected by a sparking plug located in a socket 22, but the invention is also applicable to diesel or Hot-Bulb engines Fuel may be supplied by a jet to the transfer pipe 10. The bores may contain cylinder liners having limited lateral movement to acommodate thermal expansion. The Provisional Specification refers to Specification 557,736.

Title: Improvements in or relating to alternating current uni-polar machines
IPC: H02K31/00
Filed: 1960-04-01
Abstract: 920,009. Homopolar machines. HENSCHELWERKE G.m.b.H. April 1, 1960 [April 9, 1959], No. 11683/60. Class 35. In a homopolar generator which is caused to generate A.C. by A.C. excitation of its field winding W, and in which tne rotor current is taken back across the stator pole-face to compensate for armature reaction, the collector ring through which the working flux # passes is subdivided into contact segments F to avoid circulating currents and additional stator and rotor conductors L 1  are provided for bucking the transformer voltage induced by the field fluctuations. Current collection may be made by brushes B whose number corresponds to the number of compensating conductors C, which is different from the number of rotor bars D. The width of the brushes is less than the width of insulation between the rotor collector segments, so that at all times, there is at least one break in the rotor ring. At the other end of the rotor a collector R 2  is engaged by a brush B 1 . Alternatively, collection may be by jets of conducting liquid, which are unequally spaced for the same purpose. Sparking at these brushes or jets may be avoided by connecting discharge resistances between both stator and rotor segments. This introduces resistive loss which is overcome, according to the invention by means of additional stator and rotor bars L 1  projecting axially from the contact segments F to closed rings R 1 , R<SP>1</SP> 1 . As a result of this connection the total flux entering and leaving any loop is zero, so that no transformer voltage is induced between collector segments. To save copper, the rotor conductor bar extensions L 1  and the ring R 1  are placed in the right-hand rotor immediately beside or coaxial with the working conductors D and the outer collector-ring R 2 . Additional stator bars are then not necessary. With this arrangement, both halves of the machine may constitute active conductors, the two sections being connected in series. The conductors may consist of radial plates connected to the shaft. The iron cores may be of radial plates or wire embedded in resin. The machine may be combined with a transformer. Hollow conductor-bars may be used for cooling, and the machine may be of disc form.
